<p>To protect the organisation&#8217;s assets, IT staff must first manage the device identities. IT staff can build on the device identity with tools like Microsoft Intune to ensure standards for security and compliance are met. Azure Active Directory (Azure AD) enables single sign-on to devices, apps, and services from anywhere through these devices. It&#8217;s a win-win situation for both!</p>



<ul class="wp-block-list"><li>Users get access to your organization&#8217;s assets they need.</li><li>IT staff / Security gets the controls they need to secure your organization.</li></ul>



<p><strong>Azure AD offers 3 Types of Device Registration / Joining mechanisms. </strong></p>



<ul class="wp-block-list"><li>Azure AD Registered devices</li><li>Azure AD joined devices</li><li>Hybrid Azure AD joined devices</li></ul>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>The goal of <strong>Azure AD registered devices</strong> is to provide your users with support for the BYOD or mobile device scenarios. In these scenarios, a user can access your organization’s Azure Active Directory controlled resources using a personal device. Azure AD registered devices are signed in to using a local account like a Microsoft account on a Windows 10 device, but additionally have an Azure AD account attached for access to organizational resources.</p></blockquote>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p><strong>Azure AD join</strong> is intended for organizations that want to be cloud-first or cloud-only. Azure AD join enables access to both cloud and on-premises apps and resources. Azure AD joined devices are signed in to using an organizational Azure AD account. Access to resources in the organization can be further limited based on that Azure AD account and Conditional Access policies applied to the device identity.</p></blockquote>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow"><p>Organisations with an on-premises AD footprint can implement <strong>hybrid Azure AD joined devices.</strong> These devices are joined to your on-premises Active Directory and registered with your Azure Active Directory. This offers capability to use on-premise technology like GPO, Windows auth and win 7 support etc. Device writeback helps you to keep a track of devices registered with Azure AD in AD. You will have a copy of the device objects in the container &#8220;Registered Devices&#8221;. Also, Windows Hello For Business (WHFB) requires device writeback to in Hybrid- Federated scenarios.</p></blockquote>
